People is reporting that Teen Mom star Amber Portwood, 20, was released Tuesday afternoon from the Madison County jail in Anderson, Ind. Her release comes one day after she was formally charged with three counts (two felony, one misdemeanor) of domestic battery related to alleged physical attacks against her ex-fiance Gary Shirley and one count of neglect of a dependent (their daughter Leah, 2). The court automatically entered a not guilty plea for Portwood before she was freed.
